JOURNAL JACK.

Application led March 31, 1923.

T0 all 'whom t may concern.'

Be it known that I, LEE U. HAWKINS, a citizen of the United States, residing at Madisonville, in the county of Hopkins and State of Kentucky, have invented certain new and useful Improvements in Journal Jac-ks, of which the following is a specification7 reference being had to the accompanying drawings.

This invention relates to certain improvements in journal jacks and it is an object of" the invention to provide a novel and improved device of this general character which can be readily and conveniently ap'- plied in working position and provides means whereby the boxing may be conveniently raised for the purpose of applying a new brass.

Another object of the invention is to pro vide a novel and improved device of this general character which when in applied position is supported directly by a car wheel and which is of a construction to readily permit the same to be transported by a single person.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved journal jack whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, l will now proceed to describe the same with reference to the accompanyingI drawings7 wherein Figure 1 is an elevational view illustrating a journal jack constructed in accordance with an embodiment of my invention and in applied position;

Figure 2 is a view in top plan of the structure as illustrated in Figure 1;

Figure 3 is an enlarged fragmentary view partly in section and partly in elevation illustrating a mounting for one of the liftin@ Shanks;

)igure 4t is a sectional view taken sub stantially on the line 4-4 of Figure 1;

Figure 5 is a view in perspective of the lifting plate unapplied; and o Figure G is a view partly in side elevation and partly in section of the operating mem- Serial No. 629,205.

ber for the shaft, the coacting shaft' being shown in fragment.

As herein disclosed my improved .jack comprises a plate 1 of requisitey dimensions and having its upper marginal portion a disposed on a curvature substantially similar to the peripheral curve of a wheel and said curved edge a is defined by an outstanding flange 2 adapted to overlie the tread of the wheel W when the device is in working position. rlhe flange 2 adjacent its opposite ends has freely or loosely engaged therewith the hook members which are adapted to be enga-ged over the flange 4 of the wheel W whereby the device in its entirety is effectively supported by the wheel in applied or working position.

The lower marginal portion of the plate 1 is defined by an outstanding flange 5 and said flange adjacent its opposite ends and at a point midway thereof is braced or reinforced by the webs 6, said webs being prefer ably integrally formed with the flange 5 and with the plate 1.

The webs 6 are provided with the bearings 7 for the shaft 8, said shaft being maintained in applied position by the collars 9 mounted upon said shaft and coacting with the end webs 6.

The shaft 8 at points in relatively close the wormsvl() which engage the worm wheels A or nuts 11 in contact with the flange 5 from above. The worms 11 are threaded upon the shanks 12 extending through the flange 5 from below. The lower end portions of the Shanks 12 are provided with the eyes 14 which Vare interlocked with the eyes 15 carried by the shanks or bolts 16. Threaded upon the lower or free end portions of the bolts 16 are the nuts 17.

Coacting with the bolts 16 and contacting from abovewith the nuts 17 is an elongated plate 18 which during a working operation engages the journal box from below so that upon vrequisite rotation being imparted to the shaft 8 the box will be suliiciently elevated or raised to readily permit rebrasslng. As herein disclosed one end portion of the plat-e 18 is provided with an opening 1f) through which one of the bolts 16 is engaged while the opposite end portion of the plate is provided with a longitudinally disposed open slot 2O to permit a ready engagement of the second bolt 16 with said plate.

The opposite ends of the shaft 8 terminate outwardly of the end webs 6 and are adapted to have engaged therewith an operating member M, said member as herein disclosed comprising a head 21 adapted for engagement with either end of the shaft 8, and connected with said head by a universal joint as at 22 is a handle or operating crank 23. By this means the operator can stand in the position best suited to effect the requisite rotation of the shaft 8.

From the foregoing description it is thought to be obvious that a journal jack constructed in accordance with my invention is particularly Well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modiication without departing from the principles and spirit thereof and for this reason l do not wish to be understood as limiting mysel'l;l to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

l. A journal jack of the class described comprising a plate, means carried thereby engageable with the wheels to support the device in applied position, an outstanding flange carried by the plate, a second plate adapted to underlie the journal box, shanks operatively engaged with said second plate and disposed upwardly through the llange,

members threaded upon the Shanks and engaging the flange from above, and means for rotating said members.

2. A journal jack of the class described comprising a plate, means carried thereby engageable with the wheels to support the device in applied position, an outstanding flange carried by the plate, a second plate adapted to underlie the journal box, Shanks operatively engaged with said second plate and disposed upwardly through the flange, members threaded upon the Shanks and engaging the flange from above, a shaft rotatably supported by the first named plate, and coacting means carried by said shalt and members for rotating the members.

3. A journal jack comprising a plate, means carried thereby engageable with the wheels for supporting the device in applied position, an outstanding flange carried by the plate, webs connecting the vtlange and plate, a shaft rotatably supported by the webs, threaded Shanks extending upwardly through the flange, a second plate adapted to underlie the journal box, means forcennecting the shanks and the second named plate, members threaded upon the Shanks engaging the ilange from above, and coacting means carried by said members and shaft for rotating the members upon rotation of the shaft.

In testimony whereof I hereunto aliix my signature.
